2 Claims.

This invention relates to a dispensing receptacle for volatile liquids.

An object of the invention is to provide a simple, cheap and effectivedevice of this character embodying novel and superior features ofconstruction making for advantages not hitherto obtainable in a deviceof comparable simplicity and cheapness. A more limited object is toprovide a novel means for supporting a spring operated device forclosing the dispensing opening. A further object is to provide novelspray forming means and a still further object is to provide a novelmeans for dispensing a predetermined quantity of liquid.

Other objects will be in part apparent and in part pointed outhereinafter in connection with the accompanying drawing wherein Fig. lis a part sectional elevation showing one form of my.

invention and Fig. 2 is a section corresponding substantially tothe'line 2-2 of Fig. 1.

The device consists essentially of a receptacle ID and a closureindicated generally by the numeral II. The closure ll includes a capelement l2 whichmay be threaded or otherwise secured over the neck ofthe receptacle Ill and which is provided with a central bore 13extending therethrough. Projecting upwardly from the upper surface ofthe cap element I2 is a boss I l which is externally threaded. Receivedon the boss at is a lever attaching plate i5 having a laterallyextending portion 56 provided with upstanding ears I! to which ispivoted a lever i8. Received on the boss I4 is an internally threadednozzle element it which is provided with an interior cavity 2%! and acapillary outlet opening 2i. The cavity 29, as is clear from thedrawing, constitutes an expansion chamber between the bore l3 and thecapillary opening 2|. The lever l8 carries a deformable sealing element22 which is adapted to engage the nozzle 89 in closing relation to thecapillary opening 2|. This lever is spring-pressed by a spring 23 to theposition shown in Fig. 1 and may be moved out of alignment with theopening 2! by depressing the lower end toward the receptacle I0. I havefound that by providing the expansion chamber in the passage from theinterior of the receptacle to the exterior of the nozzle, I am able toproduce a spray when using, for example, ethyl chloride which is ejectedunder the force of its own vapor pressure, and that a jet stream doesnot result as would be the case were the expansion chamber not provided.The attaching plate i5 is clamped between the nozzle l5 and the :cap' itand the portion It may be positioned at any point around the cap. Thisfeature is of importance particularly when receptacles of non-circularcross section are used.

On the interior of the cap 12 I provide a depending skirt 24 which'defines a cavity in communication with the bore l3. Within such cavity Iplace a quantity of fibrous material 25 such as cotton, wool, spunglass, metal wool or the like. I find that this material will, uponinversion of the receptacle, absorb a quantity of liquid which upondepression of the lever 18 while the receptacle is in upright positionwill be ejected under the force of the vapor pressure of the volatileliquid. This affords a convenient means of delivering a predeterminedbulk and one which may be varied by the simple expedient of placing adifferent quantity of the fibrous material in the cavity. Care must betaken not to add so much of the fibrous material that free passage ofvapors will be prevented. Indeed, I prefer to use a quantity of fibrousmaterial less than that which will result in the maximum liquidretention within the space defined by the skirt 2%, since a greaterquantity obstructs the flow of liquid without advantage. I have alsodiscovered that by the use of the fibrous material within the skirt 2tas a means oi. predetermining the bulk to be dispensed, I am able toproduce a spray even though the expansion chamber 20 is not provided.Thus in cases where the fibrous material is employed, a nozzle ofdifferent design, not providing an expansion chamber, may be employed.It is to be noted that the cavity defined by the skirt 2 5 may be of asize greater than would support any considerable quantity of liquid bycapillary attraction without the fibrous material. In the event thereceptacle is to be used for dispensing a quantity of fluid which is notpredetermined, the lever l8 may be depressed while the receptacle I0 isin inverted position whereupon an indefinite quantity of fiuid will ,beexpelled. In case the capability of dispensing a predeter-. mined bulkis not desired in any particular container, the fibrous material 25 maybe simply omitted.

It will thus be seen that I have provided a container which, whilesimple and inexpensive, lends itself readily to a wide variety of usesand while I have shown and described thepresent preferred embodiment Ido not wish to be limited to the details of the disclosure but only inaccordance with the appended claims.

Having thus described my invention, what I claim is:

l. A dispensing device comprising, in combination, a receptacle and aclosure therefor, said closure including: a cap element having a bossprojecting from the outside thereof, a bore formed in and extendingthrough said cap ele-- ment and through the bossthereof, a nozzleelement sealed over the outside of said bus and having a short capillarypassage extending to the outside thereof, and movable means normallyclosing said capillary passage and adapted to be "operated manually formovement to uncover said passage, said nozzle element and said capillaryboss defining an expansion chamber between said bore and said capillarypassage.

2. A dispensing device comprising, in combination, a receptacle'and aclosure therefor,

said closure including a cap element detachably mounted on saidreceptacle and having a boss and projecting from the outformed therewithment to uncover said capillary passage, said nozzle element and saidboss defining an expansion chamber between said bore and said capillarypassage.
